If i install this style, my extensions ( reputation system, share on, profile side switcher) don't work anymore
It's because the extensions are available only for prosilver style ?
*Edit*
Sorry, I inherited the aero to prosilver and purged all the cache and the problem was solved.

This style has no parent or template events!!! That makes it VERY incompatible with extensions. You really should add prosilver as its parent, or the lack of extension support will prevent this style from being used. And then it really should adopt all the proper template events used throughout prosilver as well. https://www.phpbb.com/styles/create/#a-events
